Synergistic insecticide mixtures

Abstract

The invention relates to insecticidal mixtures comprising, as active compounds, in each case two compounds from the series of the chloronicotinyl insecticides, and to the use of these mixtures for controlling animal pests.

Description

The present invention relates to novel active compound combinations which comprise, as active compounds, in each case two compounds from the series of the chloronicotinyl insecticides and which have very good insecticidal properties.

It is already known that chloronicotinyl insecticides can be employed for controlling animal pests, in particular insects. The chloronicotinyl insecticides include the following compounds:

imidacloprid, of the formula (I)

##STR00001##

(cf. EP 0 192 060),

clothianidin, of the formula (II),

##STR00002##

(EP 0 376 279)

dinotefuran, of the formula (III),

##STR00003##

(EP 0 649 845)

thiamethoxam, of the formula (IV),

##STR00004##

(EP 0 580 553)

thiacloprid, of the formula (V)

##STR00005##

(EP 0 235 725)

acetamiprid, of the formula (VI),

##STR00006##

(WO 91/04965)

nitenpyram, of the formula (VII),

##STR00007##

(EP 0 302 389)

While the activity of these compounds is good, it leaves something to be desired in some cases when the compounds are employed at low application rates or against specific pests.

It has now been found that mixtures comprising in each case at least two and in particular precisely two compounds from the series of the chloronicotinyl insecticides, in particular those of the formulae (I) to (VII), act synergistically and are suitable for controlling animal pests. Owing to this synergism, markedly lower amounts of active compound can be used, i.e. the activity of the mixture is greater than the activity of the individual components.

The ratio between the two active compounds employed and the total amount of mixture to be applied depends on the species and the occurrence of the insects or Acarina and can be varied within a wide range. The optimal ratios and total application rates can be determined for each application by test series.

The following mixtures according to the invention may be mentioned specifically:

All plants and plant parts can be treated in accordance with the invention. Plants are understood as meaning, in the present context, all plants and plant populations, such as desired and undesired wild plants or crop plants (including naturally occurring crop plants). Crop plants may be plants which can be obtained by conventional breeding and optimization methods or by biotechnological and genetic engineering methods or by combinations of these methods, including the transgenic plants and including the plant varieties capable or not capable of being protected by plant breeders' rights. Plant plants are understood as meaning all aerial and subterranean parts and organs of the plants, such as shoot, leaf, flower and root, examples which may be mentioned being leaves, needles, stalks, stems, flowers, fruiting bodies, fruits and seeds, and also roots, tubers and rhizomes. The plant parts also include harvested material and vegetative and generative propagation material, for example cuttings, tubers, rhizomes, slips and seeds.

What may be emphasized in this context is the particularly advantageous effect of the compositions according to the invention with regard to their use in cereal plants such as, for example, wheat, oats, barley, spelt, triticale and rye, but also in maize, sorghum and millet, rice, sugar cane, soya beans, sunflowers, potatoes, cotton, oilseed rape, canola, tobacco, sugar beet, fodder beet, asparagus, hops and fruit plants (comprising pome fruit such as, for example, apples and pears, stone fruit such as, for example, peaches, nectarines, cherries, plums and apricots, citrus fruits such as, for example, oranges, grapefruits, limes, lemons, kumquats, tangerines and satsumas, nuts such as, for example, pistachios, almonds, walnuts and pecan nuts, tropical fruits such as, for example, mango, paw-paw, pineapple, dates and bananas, and grapes) and vegetables (comprising leaf vegetables such as, for example, endives, corn salad, Florence fennel, lettuce, cos lettuce, Swiss chard, spinach and chicory for salad use, cabbages such as, for example, cauliflower, broccoli, Chinese leaves, Brassica oleracea (L.) convar. acephala var. sabellica L. (curly kale, feathered cabbage), kohlrabi, Brussels sprouts, red cabbage, white cabbage and savoy cabbage, fruit vegetables such as, for example, aubergines, cucumbers, capsicums, table pumpkins, tomatoes, courgettes and sweetcorn, root vegetables such as, for example celeriac, wild turnips, carrots, including yellow cultivars, Raphanus sativus var. niger and var. radicula, beetroot, scorzonera and celery, legumes such as, for example, peas and beans, and vegetables from the Allium family such as, for example, leeks and onions).

The treatment according to the invention of the plants and plant parts with the active compound combinations is carried out either directly or by treating their environment, habitat or store by the customary treatment methods, for example by dipping, spraying, vaporizing, misting, broadcasting, painting on and, in the case of propagation material, in particular seeds, furthermore by coating with one or more layers.

The mixtures according to the invention are particularly suitable for the treatment of seeds. Thus, most of the damage to crop plants which is caused by pests occurs as early as when the seed is infested during storage and after the seed is introduced into the soil, and during and immediately after germination of the plants. This phase is particularly critical since the roots and shoots of the glowing plants are particularly sensitive and even minor damage can lead to the death of the whole plant. Protecting the seed and the germinating plant by the use of suitable compositions is therefore of particularly great interest.

The control of pests by treating the seed of plants has been known for a long time and is subject-matter of continuous improvements. However, the treatment of seed frequently entails a series of problems which cannot always be solved in a satisfactory manner. Thus, it is desirable to develop methods for protecting the seed and the germinating plant which dispense with the additional application of crop protection products after planting or after emergence of the plants. It is furthermore desirable to optimize the amount of active compound employed in such a way as to provide optimum protection for the seed and the germinating plant from attack by pests, but without damaging the plant itself by the active compound employed. In particular, methods for the treatment of seed should also take into consideration the intrinsic insecticidal properties of transgenic plants in order to achieve optimum protection of the seed and the germinating plant with a minimum of crop protection products being employed.

The present invention therefore in particular also relates to a method for the protection of seed and germinating plants from attack by pests, by treating the seed with a composition according to the invention. The invention likewise relates to the use of the compositions according to the invention for the treatment of seed for protecting the seed and the germinating plant from pests. Furthermore, the invention relates to seed which has been treated with a composition according to the invention so as to afford protection from pests.

One of the advantages of the present invention is that the particular systemic properties of the compositions according to the invention mean that treatment of the seed with these compositions not only protects the seed itself, but also the resulting plant after emergence, from pests. In this manner, the immediate treatment of the crop at the time of sowing or shortly thereafter can be dispensed with.

A further advantage is the synergistically increased insecticidal activity of the compositions according to the invention in comparison with the respective individual active compound, which exceeds the total of the activity of the two active compounds when applied individually. This makes possible an optimization of the amount of active compound employed.

Furthermore, it must be considered as advantageous that the mixtures according to the invention can also be employed in particular in transgenic seed, the plants arising from this seed being capable of expressing a protein directed against pests. By treating such seed with the compositions according to the invention, certain pests can already be controlled by the expression of the for example insecticidal protein, and, surprisingly, the result in addition is a synergistically complemented activity together with the compositions according to the invention, which, again, increases the efficacy of the protection against attack by pests.

The compositions according to the invention are suitable for protecting seed of any plant variety as already mentioned above which is employed in agriculture, in the greenhouse, in forests, in horticulture or in viticulture. In particular, this takes the form of seed of maize, peanut, canola, oilseed rape, poppy, olive, coconut, cacao, soya beans, cotton, beet (for example sugar beet and fodder beet), rice, sorghum and millet, wheat, barley, oats, rye, sunflower, sugar cane or tobacco. The compositions according to the invention are likewise suitable for treating the seed of fruit plants and vegetables as already mentioned above. The treatment of the seed of maize, soya beans, cotton, wheat and canola or oilseed rape is of particular importance. Thus, for example, the mixture according to the invention which comprises the active compound methiocarb and imidacloprid is particularly suitable for treating the seed of maize.

As already mentioned above, the treatment of transgenic seed with a composition according to the invention is also of particular importance. This takes the form of seed of plants which, as a rule, comprise at least one heterologous gene which governs the expression of a polypeptide with in particular insecticidal properties. In this context, the heterologous genes in transgenic seed may be derived from microorganisms such as Bacillus, Rhizobium, Pseudomonas, Serratia, Trichoderma, Clavibacter, Glomus or Gliocladium. The present invention is particularly suitable for the treatment of transgenic seed which comprises at least one heterologous gene originating from Bacillus sp. and whose gene product shows activity against the European corn borer and/or the corn root worm. It is particularly preferably a heterologous gene derived from Bacillus thuringiensis.

Within the scope of the present invention, the composition according to the invention is applied to the seed either alone or in suitable formulation. Preferably, the seed is treated in a state in which it is stable enough to avoid damage during treatment. In general, the seed may be treated at any point in time between harvest and sowing. The seed usually used has been separated from the plant and freed from cobs, shells, stalks, coats, hairs or the flesh of the fruits.

When treating the seed, care must generally be taken that the amount of the composition according to the invention applied to the seed and/or the amount of further additives is chosen in such a way that the germination of the seed is not adversely affected, or that the resulting plant is not damaged. This must be borne in mind in particular in the case of active compounds which may have phytotoxic effects at certain application rates.

The compositions according to the invention can be applied directly, that is to say without comprising further components and without having been diluted. As a rule, it is preferable to apply the composition to the seed in the form of a suitable formulation. Suitable formulations and methods for the treatment of seed are known to the skilled worker and are described, for example, in the following documents: U.S. Pat. No. 4,272,417 A, U.S. Pat. No. 4,245,432 A, U.S. Pat. No. 4,808,430 A, U.S. Pat. No. 5,876,739 A, US 2003/0176428 A1, WO 2002/080675 A1, WO 2002/028186 A2.

The active compound combinations can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusts, pastes, soluble powders, granules, suspoemulsion concentrates, natural and synthetic materials impregnated with active compounds and microencapsulations in polymeric materials.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents and/or solid carriers, optionally with the use of surface-active agents, that is, emulsifiers and/or dispersants and/or foam formers.

If water is used as extender, auxiliary solvents which can be used are, for example, organic solvents. As liquid solvents, there are suitable in the main: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example mineral oil fractions, mineral and vegetable oils, alcohols, such as butanol or glycol and ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and water.

As solid carriers there are suitable:

for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates; as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifiers and/or foam formers there are suitable: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and protein hydrolysates; as dispersants there are suitable: for example lignosulphite waste liquors and methylcellulose.

Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, and natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids can be used in the formulations. Further additives may be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general comprise between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.

Preferably, the active compound combinations according to the invention comprise no further active compounds apart from the two chloronicotinyl insecticides of the formulae (I) to (VII).

If appropriate, the active compound combinations according to the invention, in commercially available formulations and in the use forms prepared from these formulations, can be present in a mixture with other known active compounds such as insecticides, attractants, sterilants, bactericides, acaricides, nematicides, fungicides, growth regulators or herbicides. The insecticides include, for example, phosphoric esters, carbamates, carboxylic esters, chlorinated hydrocarbons, phenylureas, substances produced by microorganisms, and the like.

When employed as insecticides, the active compound combinations according to the invention, in their commercially available formulations and in the use forms prepared from these mixtures, may furthermore be present in a mixture with synergists. Synergists are compounds by which the activity of the active compounds is increased without it being necessary for the syngerist added to be active itself.

The active compound content of the use forms prepared from the commercially available formulations can vary within wide ranges. The active compound concentration of the use forms can be between 0.0000001 and 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

They are applied in a customary manner adapted to suit the use forms.

When used against hygiene pests and stored-product pests, the active compound combinations are distinguished by an outstanding residual activity on wood and clay and by good stability to alkali on lime substrates.

The active compound combinations according to the invention act not only against plant pests, hygiene pests and stored-product pests, but also, in the veterinary medicine sector, against animal parasites (ectoparasites) such as hard ticks, soft ticks, mange mites, harvest mites, flies (stinging and licking), parasitic fly larvae, lice, hair lice, bird lice and fleas.

Industrial materials are understood as meaning, in the present context, non-live materials such as, preferably, polymers, adhesives, glues, paper and board, leather, wood, derived timber products and paints.

The material to be protected from attack by insects is very especially preferably wood and derived timber products.

Wood and derived timber products which can be protected by the composition according to the invention, or by mixtures comprising it, are understood as meaning, for example,

construction timber, wooden beams, railway sleepers, bridge components, jetties; wooden vehicles, boxes, pallets, containers, telephone poles, wooden claddings, windows and doors made from wood, plywood, kitboard, joiners' work or wood-based materials which, quite generally, are used in domestic construction or in joinery.

The active compound combinations can be applied as such, in the form of concentrates or generally customary formulations such as powders, granules, solutions, suspensions, emulsions or pastes.

The abovementioned formulations can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifer, dispersant and/or binder or fixative, water repellant, if appropriate desiccants and UV stabilizers and, if appropriate, colorants and pigments and other processing auxiliaries.

The insecticidal compositions or concentrates used for the protection of wood and derived timber products comprise the active compound according to the invention in a concentration of from 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amounts of compositions or concentrates employed depends on the species and the occurrence of the insects and on the medium. The optimum application rate can be determined for each application by test series. However, in general it will suffice to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of active compound based on the material to be protected.

The solvent and/or diluent used is an organochemical or solvent mixture and/or an oily or oil-type organochemical solvent or solvent mixture of low volatility and/or a polar organochemical solvent or solvent mixture and/or water and, if appropriate, an emulsifier and/or wetting agent.

Organochemical solvents which are preferably employed are oily or oil-type solvents with an evaporation number of above 35 and a flashpoint of above 30° C., preferably above 45° C. Such water-insoluble, oily and oil-type solvents of low volatility which are used are suitable mineral oils or their aromatic fractions or mineral-oil-comprising solvent mixtures, preferably white spirit, petroleum and/or alkylbenzene.

Mineral oils which are preferably used are those with a boiling range of from 170 to 220° C., white spirit with a boiling range of 170 to 220° C., spindle oil with a boiling range of 250 to 350° C., petroleum and aromatics with a boiling range of from 160 to 280° C., oil of turpentine and the like.

In a preferred embodiment, liquid aliphatic hydrocarbons with a boiling range of from 180 to 210° C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons with a boiling range of 180 to 220° C. and/or spindle oil and/or monochloronaphthalene are used, preferably α-monochloro-naphthalene.

The organic oily or oil-type solvents of low volatility and with an evaporation number of above 35 and a flasbpoint of above 30° C., preferably above 45° C., can be replaced in part by organochemical solvents of high or medium volatility, with the proviso that the solvent mixture also has an evaporation number of above 35 and a flashpoint above 30° C., preferably above 45° C., and that the insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.

In a preferred embodiment, some of the organochemical solvent or solvent mixture is replaced by an aliphatic polar organochemical solvent or solvent mixture. Aliphatic organochemical solvents which contain hydroxyl and/or ester and/or ether groups are preferably used, such as, for example, glycol ethers, esters or the like.

Organochemical binders used for the purposes of the present invention are the synthetic resins and/or binding drying oils which are known per se and which can be diluted in water and/or dissolved or dispersed or emulsified in the organochemical solvents employed, in particular binders composed of, or comprising, an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenol resin, hydrocarbon resin such as indene/coumarone resin, silicone resin, drying vegetable and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.

The synthetic resin used as binder can be employed in the form of an emulsion, dispersion or solution. Bitumen or bituminous substances may also be used as binders in amounts of up to 10% by weight. In addition, colorants, pigments, water repellants, flavour-masking agents and inhibitors or anticorrosive agents and the like, all of which are known per se, can additionally be employed.

The composition or the concentrate preferably comprises, in accordance with the invention, at least one alkyd resin or modified alkyd resin and/or a drying vegetable oil as organochemical binder. Substances which are preferably used in accordance with the invention are alkyd resins with an oil content of over 45% by weight, preferably 50 to 68% by weight.

The abovementioned binder can be replaced fully or in part by a fixative (mixture) or a plasticizer (mixture). These additives are intended to prevent volatilization of the active compounds, and also crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of binder employed).

The plasticizers are from the chemical classes of the phthalic esters, such as dibutyl phthalate, dioctyl phthalate or benzyl butyl phthalate, phosphoric esters such as tributyl phosphate, adipic esters such as di-(2-ethylhexyl) adipate, stearates such as butyl stearate or amyl stearate, oleates such as butyl oleate, glycerol ethers or high-molecular-weight glycol ethers, glycerol esters and p-toluenesulphonic esters.

Fixatives are based chemically on polyvinyl alkyl ethers such as, for example, polyvinyl methyl ether or ketones such as benzophenone, ethylenebenzophenone.

The solvent or diluent is, in particular, also water, if appropriate in a mixture with one or more of the abovementioned chemical solvents or diluents, emulsifiers and dispersants.

Particularly effective protection of timber is achieved by industrial-scale impregnating processes, for example the vacuum, the double-vacuum or pressure processes.

If appropriate, the ready-to-use compositions may additionally comprise further insecticides and, if appropriate, additionally one or more fungicides.

The active compound combinations according to the invention can at the same time be employed for protecting objects which come into contact with salt water or brackish water, in particular hulls, screens, nets, buildings, moorings and signalling system, against fouling.

Fouling sessile Oligochaeta, such as Serpulidae, and by shells and species from the Ledamorpha group (goose barnacles), such as various Lepas and Scalpellum species, or by species from the Balanomorpha group (acorn barnacles), such as Balanus or Pollicipes species, increases the frictional drag of ships and, as a consequence, leads to a marked increase in operation costs owing to higher energy consumption and additionally frequent residence in the dry dock.

Apart from fouling by algae, for example Ectocarpus sp. and Ceramium sp., in particular fouling by sessile Entomostraka groups, which come under the generic term Cirripedia (cirriped crustaceans), is of particular importance

Surprisingly, it has now been found that the active compound combinations according to the invention have an outstanding antifouling action.

The application in the field of the domestic insecticides may also be carried out in combination with other suitable active compounds such as phosphoric esters, carbamates, pyrethroids, growth regulators or active compounds from other known classes of insecticides.

The application is carried out in aerosols, unpressurized sprays, for example pump sprays and atomizer sprays, automatic misting devices, foggers, foams, gels, vaporizer products with vaporizer platelets made of cellulose or polymer, liquid vaporizers, gel and membrane vaporizers, propeller-driven vaporizers, vaporization systems which do not consume energy passive vaporization systems), moth papers, moth sachets and moth gels in the form of granules or dusts, in baits for scattering or bait stations.

When employing the active compound combinations according to the invention, the application rates can be varied within a substantial range, depending on the type of application. In the case of the treatment of plant parts, the application rates of active compound combination are generally between 0.1 and 10 000 g/ha, preferably between 10 and 1 000 g/ha.

The good insecticidal activity of the active compound combinations according to the invention can be seen from the examples which follow. While the individual active compounds show weaknesses in their activity, combinations demonstrate an activity which exceeds a simple additive effect.

The activity to be expected for a given combination of two combinations can be calculated as follows (cf. COLBY, S. R.; “Calculating synergistic and antagonistic responses of herbicide combinations”, Weeds 15, pages 20-22, 1967);

if

• • X=activity in %, destruction in comparison with the untreated control by compound A (active compound of the formula I) at a concentration of m ppm

and

• • Y=activity in %, destruction in comparison with the untreated control by compound B (active compound of the formula I) at a concentration of n ppm

and

• • E=efficacy in %, destruction in comparison with the untreated control when the mixture A and B is applied at m and n ppm,

$\mathrm{then}E=X+Y-\frac{X\times Y}{100}$

If the actual damage exceeds the calculated figure, the activity of the combination is superadditive, that is to say it demonstrates a synergistic effect.
